The Clarification of the field-oriented thought in Iranian contemporary architecture through the sociological knowledge model can be studied and analyzed as a comparative model as well as the location of the phenomena of Iranian contemporary society, especially architecture. Although sociology of knowledge must be able to control the cause of social and historical deviation in the context of Iranian architecture and identify ways by correct standards of human thought to guide the social phenomenon, such as Architectural. In this article, structural and evolutionary analysis methods and data collection tools such as in-depth interviews, observation and local navigation, documents analysis, photographs and fieldwork to observe and analyze the social behavior and cultural changes in the design of the house were used. At the end of this study, the concept of approach, methodology and understanding the operational range were mentioned, and then the impact and influence of culture on the architecture in native housing areas and vice versa in the cases of surveys area were analyzed.

Many parts of the world are affected by unusual events, natural disasters and incidents that aim for people’s life, property, and comfort and threaten their life and survival. Crises cause abundant and sometimes irreparable damages to countries and people along with adverse effects on social indexes.  Therefore, identifying, appropriate planning, and optimal Resilient crisis management are of the highest priorities in various countries. Due to its great destruction power, expansion of the destruction area, lack of the possibility of predicting the occurrence time, continued losses and threats in the form of aftershocks, extensive injuries, and numerous problems in disaster relief, considering the destruction of the infrastructural installations and essential arteries, earthquake is a very important factor in crisis management. Meanwhile, based on the existing information 69% of Iran’s surface is affected by active faults and is considered to be one of the countries prone to having earthquakes. Besides, the general weakness of structures has caused extensive casualties in disasters. In these situations control and managing crisis especially earthquakes are of extreme importance in the field of recognition, prediction and preparation before the occurrence, planning, control and guidance after the occurrence.  Obviously, achieving this aim requires rapid and simple access to correct and updated information and complicated analysis carried out by specialists and managers. On the other hand, more than 80% of the required information in crises is spatial-natured and earth-referenced. Applying GIS and related technologies can be of considerable help in collection, storage, classification and analysis of related spatial and descriptive data; and play a determining role in identifying and direct application in both prediction and prevention, and direct dealing with events.  In this article, we will study the role of GIS In planning urban Resilient and promotion helping dominate crises and their proper management, in order to reduce financial losses and injuries. Besides we try to examine the methods to identify and classify historical and worn structures with the aim of planning and priority setting of seismic improvements and retrofitting buildings against earthquakes. Given the fact that the greatest concentration of resilience in crises is on improving the city's cultural, social, economic, physical and organizational dimensions, the use of the capabilities of the GIS system is very useful given the rich information layers.

Considering the determinant role of energy efficiency opportunities in the building sector, proposing guidelines and technical solutions in order to improve the thermal performance of glazing systems is in priority in Iran and other countries. In glazing systems, a substantial amount of radiative heat transfer results from absorption and emission. Applying low-E (low emissivity) coatings on the glazing system is a solution for reducing the radiative heat transfer by radiation in glazing systems, without a noticeable decrease of visible light transmittance. By selecting the proper glazing type, in a hot climate, the amount of solar heat gain can be reduced significantly. Vice versa, in cold climate, the heat loss by long wave radiation of inner surfaces can be reduced. In this paper, first, the thermal and optical characteristics of local clear and Low-E glasses have been measured in BHRC (Road, Housing & Urban Development (National) Research Center) laboratory, by the spectrophotometer and then the thermal performance of single and double glazing units, with and without low-E coating, in different orientations (North, South, East and West) are computed, compared and analyzed for cold (Ardebil) and hot (Bandar-Abbas) climates in Iran. The selection of these two cities is based on maximum heating and cooling degree day values obtained respectively for Ardebil and Bandar-Abbas. The simulation results indicate that using double clear glazing unit with low-E coating reduces the energy consumption significantly in very hot climates, using mostly electrical energy for cooling. In cold climates like Ardebil, double glazing with low-E coating has a minor impact on annual heating load, because of the great amount of thermal radiation, even in the cold season, the high cost of low-e coating and the considerable payback time, compared to the building life cycle.
